RCBS UPM-3 Competition Powder Measure

RCBS UPM-3 Competition Powder Measure

The RCBS UPM-3 represents the evolution of the proven Uniflow Powder Measure, engineered specifically for reloaders who demand consistency and precision. This is a tool built on the principle that accurate powder charges are the foundation of reliable ammunition.

Key Features

Precision Metering System

• Single metering cylinder handles both rifle and pistol powders
• Meters charges from 0.5 to 100 grains
• Achieves 0.10 grain accuracy with micrometer adjustment
• Powder baffle controls flow and column pressure for consistent results

Micrometer Adjustment The micrometer adjustment screw allows you to fine-tune your charge weight with precision. More importantly, it lets you record your settings for future reference—a feature that saves time and eliminates guesswork when you return to a particular load.

Practical Design

• Ambidextrous handle positions for right or left-handed operation
• Cast iron construction for durability and stability
• 1-pound hopper capacity
• Threaded hopper for easy removal and cleaning
• Quick-change drain attachment for efficient powder management
• Includes two drop tubes and drain attachment

Important Notes

This powder measure should always be used in conjunction with an accurate powder scale to set your initial charge and verify loads periodically during reloading sessions. Never use this measure with black powder.

The UPM-3 is designed for serious reloaders who understand that precision in every step produces superior ammunition.
